I claim priority of my three U.S. Provisional Applications Ser. No. 60\484990 filed Jul. 3, 2003; Ser. No. 60\495641 filed Aug. 15, 2003; and Ser. No. 60\502456 filed Sep. 11, 2003.
This invention relates to improvements in gaming devices, and particularly to the game of roulette.
In the game of roulette, which is played at many gaming houses in the United States and elsewhere, a dealer employed by the gaming house releases a ball which then travels around the periphery of a rotating wheel having circumferentially arranged pockets, until the ball finally stops in a particular pocket. The stopping place of the ball, and a number associated with that stopping place, determines whether particular players have won or lost on their bets, and whether the house has won or lost.
Although it is perhaps a groundless concern, some players worry that the dealer, because of greater familiarity with the apparatus and its mode of operation, may be able to cause the ball to stop at a location favorable to the house but which will cause the players to lose.
Many players may therefore wish for a procedure that would ensure that the dealer cannot and has not “rigged” the play.
According to the invention I have provided a method and apparatus for a roulette game, wherein a ball is launched about the periphery of a rotating wheel having circumferentially arranged pockets, and wherein the final stopping of the ball in a particular pocket determines a win or loss result. My method and apparatus ensures that the dealer cannot and has not “rigged” the play.
According to my novel method the ball is launched in such a way that the dealer in charge of the game has no direct physical contact with the ball during either its launch or its subsequent travel, and no control over where the ball might stop.
Further according to my novel method, a mechanical launch mechanism is selected which is capable of launching the ball along a desired path about the wheel periphery; an electronic random time delay device is selected that is capable of energizing the launch mechanism at a random time delay after it has itself been energized; and an isolated manually actuable activation means is utilized for generating a start signal to then energize the electronic random time delay device. When it is desired to launch the ball, therefore, the isolated manually actuable activation means is energized, so that the person who actuates it is unable to either predict or control either the exact time the ball will be launched or its ultimate stopping place.
According to my invention any of a number of different means may be utilized for communicating a start signal to the electronic random time delay device, including a hard-wired circuit, a radio transmitter, an infrared remote control, or the like.
Further according to my invention, any of a number of different launch mechanisms may be utilized for the launching of the ball. The launching may be propelled by an electromagnetic action, by a release of air pressure, by spring action, or other suitable means.
Still further in accordance with my invention, I provide an apparatus which may be retrofitted into an existing roulette game table and which may then be used to carry out the purposes of my invention.
Referring now to the drawings,
In accordance with the invention a random time period is generated by electronic circuitry as shown in
D flip-flop 30 has an input 31 which receives an Enable signal on output 27 from the latch 25, and an input 32 which receives the output signal of the square-wave generator 20. It also has a primary output terminal 33 from which a launch signal 40 is to be generated. The operation of the D flip-flop is such that an output signal on terminal 33 is only possible after the signal on input 32 has raised from low to high voltage level. In other words, if the input signal received on terminal 32 from square-wave generator 20 is already high at the time the Enable signal starts, then nothing else will happen; flip-flop 30 will not then produce an output until its square-wave input on terminal 32 goes down to its lower voltage level and then later rises to the higher level.
The time interval between time t1 and time t2 is a randomly generated time interval. It will be understood that the operation of square wave generator 20 is not synchronized with anything else in the circuitry. The square wave genereator may, for example, be a free-running multivibrator with either equal or unequal time periods for its two output states. Alternatively, a high-frequency oscillator could be utilized with a frequency divider circuit to create a low frequency square wave output on terminal 32. By selecting a desired time period for the low voltage level output of generator 20 it is possible to generate random time delays that may be a very small fraction of a second, or as much as several seconds, as may be desired. The random time delay interval will never exceed the duration of the low voltage level of the low frequency square wave output on terminal 32.
Clock Signal generator 50 is an independent circuit. The clock frequency is selected to be at least many times the frequency of the square wave output signal of generator 20. When the signal received on terminal 32 goes from low to high, there may then have been a rather large number of clock pulses which the counter 45 would have counted before the output signal of the generator 20 goes low again. The time delay count displayed on the readout device 18 may be calibrated in any desired units, since players or customers for the game will be primarily interested in seeing that the time delays are random and not pre-programmed.
Latching flip-flop 25 performs the function of receiving and storing the Start Game signal 16 generated from the remote transmitter 14, shown in
Readout from display 18 is available from the time that the counting starts until the high output voltage level from D flip-flop 30 ends, at which time complementary output terminal 34 of the flip-flop generates a signal indicating that the count should be stopped. This signal on terminal 34 is combined through an “and” gate 57 with the output of latch 25, to instruct counter circuit 45 to stop counting. The accumulated time count will then remain visible for a period of time.
When the ball has stopped, and its stoppage has been electronically detected, one of the inputs required for “and” gate 60 is satisfied. The other requirement is a Reset Game signal on input line 61. When these two inputs co-exist, gate 60 then produces a negative output pulse acting as a reset signal which is delivered to each of three different places to return the circuitry to initial starting condition. One of those three destinations is latch 25; another is D flip-flop 30; and the third is counter 45.
It is desirable for the random time count displayed in device 18 to remain visible for some period of time after the ball has stopped, in order to allow the players or customers adequate time to see and understand the random time delay count.
With the circuitry as presently illustrated it is necessary for the dealer (or someone else) to send a Game Reset signal on input line 61; then, it is also necessary to push the remote button 15 in order to actually start a new game by again launching the ball. It would be possible to combine start button 15 and reset game line 61 into a single control, but that would not be the preferred approach.

Referring now to
Method of Operation. Before a game is started it is necessary for the dealer to place the ball in the extreme forward end of opening 80 where it may be engaged by plunger 72. Then a Reset Game signal is applied to line 61. The apparatus is now ready to start a game. The next step is for the dealer—or a player or customer—to push the remote button 15. This causes flip-flop 25 to latch in the Enable state, at time t1. When the output wave of square-wave generator 20 again rises to its high level, at time t2, a launch signal 40 will be generated and plunger 72 will launch the ball. At the same time, the counter 45 will have accumulated a count indicative of the random time delay that has transpired between the pushing of button 15 and the application of a launch energize signal to launch mechanism 12. A count that represents the random time delay is then visibly displayed in the display device 18. The dealer may then reposition the ball in preparation for another game. The time delay display will remain until another Game Reset signal is applied to line 61.
The presently preferred embodiment of my invention has been disclosed in detail in order to comply with requirements of the patent laws. It will be understood, however, that other modifications and variations will be understood by persons who are skilled in the art, and that the scope of my invention is to be judged only in accordance with the appended claims.
